Description

Technical Field

[0001] The invention relates to the technical field of coating processing, and in particular to a film vibration blocking device and a double-release and double-receive coating production line. Background Art

[0002] The coating production line is an automated production equipment used to coat specific materials on various film substrates. It uses unwinding, coating, drying, winding and other devices to form a coating uniformly on the surface of the film. At present, an air flotation oven is often used in the coating production line to dry the coating on the film. After the coating device in the coating production line coats the coating on the surface of the film, the film will enter the air flotation oven for drying. The air flotation oven uses an air nozzle to suspend the film in the oven to avoid contact between the film and the inner wall of the oven, and the hot air blown out from different directions in the oven can evenly dry the coating on the surface of the film to achieve the purpose of drying the coating. In the prior art, the speed and pressure of the air flow at the inlet of the air flotation oven may fluctuate. This unstable airflow will impact the film entering the air flotation oven, causing the film to vibrate at the moment of entering the air flotation oven, resulting in the vibration of the film in the air flotation oven being transmitted to the film at the coating device. The vibration of the film at the coating device will cause the gap between the coating device and the film to vibrate, making it impossible for the coating device to evenly coat the coating on the film, thereby making the deposition amount of the coating on the surface of the film unstable, resulting in uneven thickness of the coating coated on the film by the coating device, which is not conducive to improving the coating quality of the coating device. Summary of the invention

[0022] refer to Figures 1 to 3 and Fig. 9 The present invention discloses a film vibration blocking device, including a frame 500 and two clamping and moving mechanisms 100. The two clamping and moving mechanisms 100 are both arranged on the frame 500, and the two clamping and moving mechanisms 100 are respectively used to clamp the two sides in the width direction of the film. The clamping and moving mechanism 100 includes an annular slide rail 400, a driving component 200, a second top block 430 and a plurality of clamping components 300, and the plurality of clamping components 300 can be slidably connected to the annular slide rail 400, and the plurality of clamping components 300 are connected to the output end of the driving component 200, and the driving component 200 is used to drive the plurality of clamping components 300 to cyclically move on the annular slide rail 400, and the annular slide rail 400 has a first straight segment 410, and the plurality of clamping components 300 on the first straight segment 410 can move along the conveying direction of the film. The second top block 430 moves in the direction of rotation, the moving speeds of the multiple clamping assemblies 300 on the first straight segment 410 are the same as the conveying speed of the film, the length direction of the second top block 430 is parallel to the first straight segment 410, the length of the second top block 430 is less than the length of the first straight segment 410, the second top block 430 is arranged above the first straight segment 410, and the lower surface of the second top block 430 can simultaneously abut against the clamping assemblies 300 on the first straight segment 410, so that part of the clamping assemblies 300 on the first straight segment 410 can clamp one side of the film.

[0023] In the embodiment of the present invention, reference Figure 1 , Figure 4 and Fig. 9, the film is transported from back to front, that is, the transport direction of the film is parallel to the front-to-back direction, and the width direction of the film is the left-right direction. The film vibration blocking device of the embodiment of the present invention is installed between the coating device 20 and the air flotation oven 10, and the film vibration blocking device is close to the entrance of the air flotation oven 10. The film vibration blocking device includes a frame 500 and two clamping and moving mechanisms 100, and the frame 500 is used to be arranged between the coating device 20 and the air flotation oven 10, and the frame 500 is close to the entrance of the air flotation oven 10. The two clamping and moving mechanisms 100 are both arranged on the frame 500, and the gap between the two clamping and moving mechanisms 100 is used for allowing the film to move from back to front, that is, the two clamping and moving mechanisms 100 are respectively located on the left and right sides of the film, so that the two clamping and moving mechanisms 100 can clamp the left and right sides of the film respectively, and the moving speed and direction of the two clamping and moving mechanisms 100 are the same as the transport speed and direction of the film.

[0024] refer to Figure 5 and Figure 6 , the two clamping and moving mechanisms 100 each include an annular slide rail 400, a driving assembly 200, a second top block 430 and a plurality of clamping assemblies 300. Here, one of the clamping and moving mechanisms 100 is used for illustration. Figure 5 , Figure 6 and Fig. 9 In the embodiment of the present invention, the annular slide rail 400 has a first straight segment 410, a second straight segment, a first arc segment and a second arc segment. The first straight segment 410 and the second straight segment are parallel to the front-to-back direction. The front ends of the first straight segment 410 and the second straight segment are respectively connected to the two ends of the first arc segment, and the rear ends of the first straight segment 410 and the second straight segment are respectively connected to the two ends of the second arc segment. The first straight segment 410 is close to the film. Multiple clamping assemblies 300 can be slidably connected to the annular slide rail 400, and the multiple clamping assemblies 300 are evenly distributed on the annular slide rail 400. In other words, the multiple clamping assemblies 300 can slide on the first straight segment 410, the second straight segment, the first arc segment and the second arc segment. Reference Figure 1 and Fig. 9 The area between the first straight sections 410 of the two annular slide rails 400 is used for the film to pass through.

[0025] refer to Figure 5 and Figure 6, the driving assembly 200 is arranged on the frame 500, and the output end of the driving assembly 200 is connected to the multiple clamping assemblies 300 at the same time, so that the driving assembly 200 can simultaneously drive the multiple clamping assemblies 300 to move cyclically on the closed-loop annular slide rail 400, that is, the multiple clamping assemblies 300 can move cyclically on the first straight segment 410, the second straight segment, the first arc segment and the second arc segment. In the embodiment of the present invention, when the clamping assembly 300 moves to the first straight segment 410, the moving direction of the clamping assembly 300 will be consistent with the conveying direction of the film, that is, the moving directions of the multiple clamping assemblies 300 moving to the first straight segment 410 are all the same as the conveying direction of the film, and the moving speeds of the multiple clamping assemblies 300 moving to the first straight segment 410 are all the same as the conveying speed of the film. In the embodiment of the present invention, the length direction of the second top block 430 is the same as the length direction of the first straight segment 410, and the length of the second top block 430 is less than the length of the first straight segment 410. In other words, the front end of the second top block 430 is located behind the front end of the first straight segment 410, and the rear end of the second top block 430 is located in front of the rear end of the first straight segment 410. The second top block 430 is arranged on the frame 500, and the second top block 430 is located above the first straight segment 410, so that the lower surface of the second top block 430 can be simultaneously abutted against the multiple clamping assemblies 300 on the first straight segment 410. Under the action of the second top block 430, the multiple clamping assemblies 300 on the first straight segment 410 can clamp one side of the film while moving.

[0026] It can be understood that the film vibration blocking device is installed between the coating device 20 and the air flotation oven 10. The film vibration blocking device includes two clamping and moving mechanisms 100. The two clamping and moving mechanisms 100 can clamp the two sides of the film respectively, so that the film clamped by the two clamping and moving mechanisms 100 will not vibrate, thereby blocking the vibration of the film in the air flotation oven 10 from being transmitted to the film at the coating device 20. Specifically, the two clamping and moving mechanisms 100 each include an annular slide rail 400, a driving assembly 200, a second top block 430 and a plurality of clamping assemblies 300. During the film conveying process, the driving assembly 200 can drive the plurality of clamping assemblies 300 to circulate on the annular slide rail 400. When the clamping assembly 300 moves to the first straight segment 410, the clamping assembly 300 will abut against the lower surface of the second top block 430 above the first straight segment 410. Under the action of the second top block 430, the clamping assembly 300 clamps one side of the film, and under the action of the driving assembly 200, the moving directions of the multiple clamping assemblies 300 on the first straight segment 410 are consistent with the conveying direction of the film, and the moving speeds of the multiple clamping assemblies 300 on the first straight segment 410 are consistent with the conveying speed of the film, that is, the multiple clamping assemblies 300 on the first straight segment 410 move along with the film while clamping the film, thereby avoiding the relative displacement between the multiple clamping assemblies 300 on the first straight segment 410 and the film. Under the clamping action of the multiple clamping assemblies 300 on the first straight segment 410, the film near the entrance of the air-floating oven 10 will not vibrate, and the vibration of the film in the air-floating oven 10 is blocked from being transmitted to the film at the coating device 20, so that the film at the coating device 20 can be smoothly conveyed, and then the coating device 20 can evenly coat the coating on the film, which is conducive to ensuring the coating quality of the coating device 20.

[0027] refer to Figures 1 to 4, as the clamping assembly 300 moves, the clamping assembly 300 will be separated from the contact with the second top block 430. After the clamping assembly 300 is separated from the contact with the second top block 430, the clamping assembly 300 will release the film and leave the first straight segment 410, and this cycle is repeated, so that the clamping assembly 300 can clamp the film and move synchronously with the film after moving to the first straight segment 410, and can also release the film after the clamping assembly 300 is about to leave the first straight segment 410. It should be explained that since the length of the second top block 430 is less than the length of the first straight segment 410, the clamping assembly 300 needs to move a distance after moving to the first straight segment 410 to abut against the lower surface of the second top block 430, that is, after the clamping assembly 300 moves to the first straight segment 410, it needs to move a distance before it can clamp one side of the film. After the clamping assembly 300 is separated from the abutment with the second top block 430, the clamping assembly 300 is still located on the first straight segment 410, and the clamping assembly 300 needs to move a certain distance to leave the first straight segment 410, that is, after releasing the film, the clamping assembly 300 needs to move a certain distance to leave the first straight segment 410.

[0028] In the embodiment of the present invention, the clamping assembly 300 moves synchronously with the film during the process of clamping the film, thereby avoiding relative displacement between the clamping assembly 300 and the clamped film, thereby avoiding wrinkles in the film. It should be explained that the coating device 20 only coats the middle area of ​​the film, and no coating is applied on both sides of the film in the width direction, that is, no coating is applied to the area clamped by the clamping assembly 300.

[0029] It should be explained that, in the embodiment of the present invention, the two clamping moving mechanisms 100 are arranged in a mirror image, and the multiple clamping components 300 on the first straight line segments 410 in the two clamping moving mechanisms 100 are arranged one by one, that is, both sides of the film in the width direction are clamped by multiple corresponding clamping components 300 at the same time. On the one hand, since both sides of the film are clamped by multiple clamping components 300, the film cannot be displaced in the left and right and up and down directions under the clamping limit of the clamping components 300. On the other hand, since the moving directions and moving speeds of the multiple clamping components 300 on both sides of the film are consistent with the conveying speed of the film, the film cannot move in the front and back directions either. In other words, the multiple clamping assemblies 300 on both sides prevent the clamped film from being displaced in the left-right and up-down directions, and also prevent the clamped film from moving in the front-to-back direction. The multiple clamping assemblies 300 on both sides also increase the tension of the clamped film, so that the clamped film cannot vibrate, thereby making the clamped film have a vibration blocking effect, thereby preventing the vibration of the film in the air flotation oven 10 from being transmitted to the film at the coating device 20.

[0030] refer to Figure 6 and Figure 7 The clamping assembly 300 includes a slider 350, a first clamping arm 310, a second clamping arm 320 and an elastic member 330. The slider 350 can be slidably connected to the annular slide rail 400. The slider 350 is connected to the output end of the driving assembly 200. The first clamping arm 310 is arranged on the slider 350, and the second clamping arm 320 is movably connected to the slider 350. An elastic member 330 is arranged between the first clamping arm 310 and the second clamping arm 320. The gap between the first clamping arm 310 and the second clamping arm 320 is used for one side of the film to extend into. The second clamping arm 320 can abut against the lower surface of the second top block 430 to make the second clamping arm 320 close to the first clamping arm 310. The second clamping arm 320 can be separated from the abutment with the second top block 430, so that the elastic member 330 can drive the second clamping arm 320 away from the first clamping arm 310, and make the first clamping arm 310 and the second clamping arm 320 release one side of the film. In the embodiment of the present invention, the plurality of clamping assemblies 300 each include a slider 350, a first clamping arm 310, a second clamping arm 320 and an elastic member 330. The sliders 350 in the plurality of clamping assemblies 300 are all connected to the output end of the driving assembly 200, so that the driving assembly 200 can drive the plurality of sliders 350 to cyclically move on the annular slide rail 400, and the lower surface of the second top block 430 can simultaneously abut against the second clamping arms 320 in the plurality of clamping assemblies 300 on the first straight segment 410. Here, one of the clamping assemblies 300 is used for illustration. The slider 350 can be slidably connected to the annular slide rail 400, that is, the slider 350 can slide on the first straight segment 410, the second straight segment, the first arc segment and the second arc segment. The first clamp arm 310 is disposed on the slider 350, the second clamp arm 320 is located above the first clamp arm 310, the lower end of the elastic member 330 is connected to the first clamp arm 310, and the upper end of the elastic arm is connected to the second clamp arm 320, so that the film can extend between the first clamp arm 310 and the second clamp arm 320. In the embodiment of the present invention, the elastic member 330 is a compression spring.

[0031] Since the length of the second top block 430 is less than the length of the first straight segment 410, after the slider 350 enters the first straight segment 410, the first clamp arm 310 and the second clamp arm 320 are still in an open state, and at this time, one side of the film has extended between the first clamp arm 310 and the second clamp arm 320. As the slider 350 moves, the second clamp arm 320 begins to abut against the lower surface of the second top block 430. Under the limiting effect of the second top block 430, the second clamp arm 320 moves downward and the elastic member 330 begins to compress, so that the second clamp arm 320 approaches the first clamp arm 310, thereby enabling the first clamp arm 310 and the second clamp arm 320 to clamp the film, and the first clamp arm 310 and the second clamp arm 320 move synchronously with the film. As the slider 350 continues to move, the second clamp arm 320 is separated from the contact with the second top block 430. At this time, under the pushing action of the elastic member 330, the second clamp arm 320 rises and moves away from the first clamp arm 310, so that the first clamp arm 310 and the second clamp arm 320 release one side of the film. At this time, the slider 350 is still located on the first straight segment 410. As the slider 350 continues to move, the slider 350, the first clamp arm 310 and the second clamp arm 320 leave the first straight segment 410. In the embodiment of the present invention, when the slider 350 is on the first arc segment, the second straight segment and the second arc segment, the first clamp arm 310 and the second clamp arm 320 are both in an open state.

[0032] refer to Figure 4 , Figures 6 to 8 The clamping moving mechanism 100 also includes a first top block 440, which is arranged on the frame 500, and the first clamping arm 310 is movably connected to the slider 350. The first clamping arm 310 and the second clamping arm 320 can respectively abut against the first top block 440 and the second top block 430 at the same time, so that the first clamping arm 310 and the second clamping arm 320 are close to each other and clamp one side of the film, and the first clamping arm 310 and the second clamping arm 320 can respectively break away from the abutment with the first top block 440 and the second top block 430 at the same time, so that the elastic member 330 drives the first clamping arm 310 and the second clamping arm 320 to move away from each other and release one side of the film. In an embodiment of the present invention, the first top block 440 is arranged on the side of the first straight line segment 410 close to the film, and the first clamping arm 310 can be against the upper surface of the first top block 440 so that the first clamping arm 310 can rise, the first top block 440 and the second top block 430 have the same length, and the first top block 440 and the second top block 430 are arranged in a mirror image.

[0033] It is understandable that after the slider 350 enters the first straight section 410, the first clamp arm 310 and the second clamp arm 320 are still in an open state, and at this time, one side of the film has already extended between the first clamp arm 310 and the second clamp arm 320. As the slider 350 moves, the first clamp arm 310 begins to abut against the upper surface of the first top block 440, and the second clamp arm 320 begins to abut against the lower surface of the second top block 430. Under the limiting action of the first top block 440 and the second top block 430, the first clamp arm 310 rises, the second clamp arm 320 falls, and the elastic member 330 begins to compress, so that the first clamp arm 310 and the second clamp arm 320 are close to each other, so that the first clamp arm 310 and the second clamp arm 320 can clamp the film, and the first clamp arm 310 and the second clamp arm 320 move synchronously with the film. As the slider 350 continues to move, the first clamp arm 310 and the second clamp arm 320 are separated from the contact with the first top block 440 and the second top block 430 respectively. At this time, under the pushing action of the elastic member 330, the first clamp arm 310 descends, the second clamp arm 320 rises, and the elastic member 330 stretches, so that the first clamp arm 310 and the second clamp arm 320 move away from each other, thereby making the first clamp arm 310 and the second clamp arm 320 release one side of the film. At this time, the slider 350 is still located on the first straight segment 410, and one side of the film is still arranged between the first clamp arm 310 and the second clamp arm 320. As the slider 350 continues to move, the slider 350, the first clamp arm 310 and the second clamp arm 320 leave the first straight segment 410. In the embodiment of the present invention, when the slider 350 is on the first arc segment, the second straight segment and the second arc segment, the first clamp arm 310 and the second clamp arm 320 are both in an open state. The structures of the first top block 440 and the second top block 430 are completely the same, and the only difference is that the first top block 440 is used to make the first clamping arm 310 rise, which will not be further described here. In the embodiment of the present invention, under the action of the first top block 440 and the second top block 430, the first clamping arm 310 and the second clamping arm 320 can rise and fall respectively at the same time, so that the first clamping arm 310 and the second clamping arm 320 can be against the film at the same time, so as to avoid the first clamping arm 310 and the second clamping arm 320 applying a drag force in the up and down directions to the film in the process of clamping the film.

[0034] refer to Figures 1 to 3 , Figure 8 A first guiding slope (not shown) is disposed on one end of the first top block 440, and the first clamping arm 310 can abut against the first guiding slope, so that the first clamping arm 310 can abut against the upper surface of the first top block 440. A second guiding slope 431 is disposed on one end of the second top block 430, and the second clamping arm 320 can abut against the second guiding slope 431, so that the second clamping arm 320 can abut against the lower surface of the second top block 430. Figure 2 and Figure 3, a first buffer slope (not shown) is provided on the other end of the first top block 440, and a second buffer slope 432 is provided on the other end of the second top block 430. The first clamp arm 310 and the second clamp arm 320 can respectively abut against the first buffer slope 432 at the same time to slow down the speed at which the first clamp arm 310 and the second clamp arm 320 move away from each other. In the embodiment of the present invention, a first guide slope is provided at the rear end of the first top block 440, a second guide slope 431 is provided at the rear end of the second top block 430, a first buffer slope is provided at the front end of the first top block 440, and a second buffer slope 432 is provided at the front end of the second top block 430. The angle formed by the first buffer slope and the first guide slope is downward, and the angle formed by the second buffer slope 432 and the second guide slope 431 is upward.

[0035] After the slider 350 enters the first straight section 410, as the slider 350 continues to move, the first clamp arm 310 begins to abut against the first guide slope on the rear end of the first top block 440, and the second clamp arm 320 begins to abut against the second guide slope 431 on the rear end of the second top block 430. Under the guidance of the first guide slope 431 and the second guide slope 431, the first clamp arm 310 gradually rises and the second clamp arm 320 gradually falls, so that the first clamp arm 310 and the second clamp arm 320 gradually approach each other. As the slider 350 continues to move, the first clamp arm 310 and the second clamp arm 320 simultaneously separate from the abutment with the first guide slope 431 and the second guide slope 431, and simultaneously abut against the upper surface of the first top block 440 and the lower surface of the second top block 430, so that the first clamp arm 310 and the second clamp arm 320 clamp one side of the film.

[0036] As the slider 350 continues to move, the first clamp arm 310 and the second clamp arm 320 are separated from the contact with the upper surface of the first top block 440 and the lower surface of the second top block 430 respectively and simultaneously, and respectively contact with the first buffer slope 432 and the second buffer slope 432. Under the buffering effect of the first buffer slope 432, the descending speed of the first clamp arm 310 slows down, and the ascending speed of the second clamp arm 320 slows down, so that the speed at which the first clamp arm 310 and the second clamp arm 320 move away from each other slows down, thereby enabling the first clamp arm 310 and the second clamp arm 320 to release the film more smoothly, so as to reduce the impact force on the film during the release process, and effectively avoid the film from shaking or vibrating due to sudden force changes caused by the sudden release. On the other hand, the slow release of the first clamp arm 310 and the second clamp arm 320 can better protect the integrity and stability of the film, that is, the slow release can prevent the film from breaking due to the stress caused by the rapid release.

[0037] As an embodiment of the present invention, the clamping assembly 300 further includes a first roller and a second roller, which are rotatably connected to the first clamp arm 310 and the second clamp arm 320, respectively. The first clamp arm 310 abuts against the first guide slope, the upper surface of the first top block 440, and the second buffer slope 432 through the first roller, and the second clamp arm 320 abuts against the second guide slope 431, the lower surface of the second top block 430, and the second buffer slope 432 through the second roller. It can be understood that the first roller can reduce the friction between the first clamp arm 310 and the first top block 440, and the second roller can reduce the friction between the second clamp arm 320 and the second top block 430.

[0038] refer to Figures 6 to 8 The clamping assembly 300 further includes a plurality of guide posts 340. The first clamping arm 310 is provided with a plurality of first guide holes. The second clamping arm 320 is provided with a plurality of second guide holes. The lower ends of the plurality of guide posts 340 are respectively inserted into the plurality of first guide holes. The lower ends of the plurality of guide posts 340 are all connected to the slider 350. The upper ends of the plurality of guide posts 340 are respectively inserted into the plurality of second guide holes. The clamping assembly 300 includes a plurality of elastic members 330. The plurality of elastic members 330 are respectively sleeved on the plurality of guide posts 340. The upper and lower ends of the elastic members 330 are respectively against the second clamping arm 320 and the first clamping arm 310. It can be understood that the lower ends of the plurality of guide pillars 340 are respectively inserted into the plurality of first guide holes on the first clamp arm 310, and the upper ends of the plurality of guide pillars 340 are respectively inserted into the plurality of second guide holes on the second clamp arm 320. The plurality of guide pillars 340 can guide the first clamp arm 310 and the second clamp arm 320, so that the first clamp arm 310 and the second clamp arm 320 can be lifted and lowered smoothly. There are a plurality of elastic members 330, and the plurality of elastic members 330 are respectively sleeved on the plurality of guide pillars 340. The guide pillars 340 can guide the elastic members 330, so that the elastic members 330 can be compressed and stretched smoothly. In the embodiment of the present invention, the first clamp arm 310 is provided with a plurality of receiving grooves, and the plurality of receiving grooves are respectively connected to the plurality of first guide holes, and the lower ends of the plurality of guide pillars 340 are respectively inserted into the plurality of receiving grooves, and the lower ends of the plurality of elastic members 330 are respectively connected to the inner bottom walls of the plurality of receiving grooves. After the elastic member 330 is compressed, the elastic member 330 in the compressed state can completely enter the receiving groove to prevent the elastic member 330 from interfering with the first clamping arm 310 and the second clamping arm 320, so that the first clamping arm 310 and the second clamping arm 320 can smoothly clamp the film.

[0039] refer to Figure 6The driving assembly 200 includes a motor, a synchronous belt 210, a driven pulley 220 and a driving pulley 230. The motor is arranged on the frame 500. The driven pulley 220 and the driving pulley 230 are both arranged in the area surrounded by the annular slide rail 400. The driven pulley 220 and the driving pulley 230 are both rotatably connected to the frame 500. The synchronous belt 210 is wound around the driven pulley 220 and the driving pulley 230. The synchronous belt 210 is connected to a plurality of clamping assemblies 300. The motor is used to drive the driving pulley 230 to rotate, so that the synchronous belt 210 can drive the plurality of clamping assemblies 300 to circulate on the annular slide rail 400. It can be understood that the synchronous belt 210 is connected to the sliders 350 in the plurality of clamping assemblies 300. The motor drives the driving pulley 230 to rotate, so that the synchronous belt 210 and the driven pulley 220 rotate together. Since the synchronous belt 210 is connected to the sliders 350 in the plurality of clamping assemblies 300, the rotating synchronous belt 210 can drive the plurality of sliders 350 to move cyclically on the annular slide rail 400. In the embodiment of the present invention, the driven pulley 220 and the driving pulley 230 are arranged on the frame 500 along the front-to-back direction, so that the portion of the synchronous belt 210 wound around the driven pulley 220 and the driving pulley 230 is parallel to the front-to-back direction. In the embodiment of the present invention, the output power of the motor is constant, so that the rotation speed of the driving pulley 230, the driven pulley 220 and the synchronous belt 210 is constant, and thus the moving speed of the plurality of sliders 350 on the first straight segment 410 is constant, and the moving speed of the plurality of sliders 350 on the first straight segment 410 is the same as the conveying speed of the film.

[0040] In the embodiment of the present invention, the film vibration blocking device further includes a speed sensor, which is used to detect the conveying speed of the film in real time. The speed sensor is electrically connected to the motor so that the output power of the motor can be adjusted according to the conveying speed of the film. It can be understood that the speed sensor can detect the real-time conveying speed of the film, and the motor will adjust the output power according to the current conveying speed of the film, so that the speed of the multiple sliders 350 on the first straight segment 410 can always be consistent with the conveying speed of the film, so as to avoid relative displacement between the first clamping arm 310 and the second clamping arm 320 and the film.

[0041] As an embodiment of the present invention, the driving assembly 200 further includes two limit plates, both of which are parallel to the first straight segment 410, and both of which are arranged on the frame 500, and the gap between the two limit plates is used for a portion of the synchronous belt 210 to pass through. It can be understood that the lengths of the two limit plates are parallel to the first straight segment 410, and both of which are arranged between the driven pulley 220 and the driving pulley 230, and the gap between the two limit plates is used for a portion of the synchronous belt 210 to pass through, so that the two limit plates can limit the portion of the synchronous belt 210, thereby enabling the portion of the synchronous belt 210 to remain straight and parallel to the front-rear direction, so as to ensure that the portion of the synchronous belt 210 can smoothly drive the multiple sliders 350 on the first straight segment 410 to move, and ensure that the speed of the multiple sliders 350 on the first straight segment 410 does not fluctuate. In the embodiment of the present invention, the driving assembly 200 further includes a tensioning sprocket, which is rotatably connected to the frame 500, and is disposed in the area surrounded by the annular slide rail 400. The tensioning sprocket abuts against the synchronous belt 210 to increase the tension of the synchronous belt 210. The function of the tensioning sprocket will not be further described here.

[0042] As an embodiment of the present invention, the two clamping moving mechanisms 100 can be slidably connected to the frame 500 so that the distance between the two clamping moving mechanisms 100 is adjustable. It can be understood that the two clamping moving mechanisms 100 can be slidably connected to the frame 500 in the left and right directions, so that the distance between the two clamping moving mechanisms 100 can be adjusted according to the films of different widths, thereby enabling the two clamping moving mechanisms 100 to clamp films of different widths, which is conducive to improving the flexibility of use of the film vibration blocking device. As an embodiment of the present invention, the film vibration blocking device also includes a screw nut driving assembly 200 and two bases, both of which can be slidably connected to the frame 500, and the two clamping moving mechanisms 100 are respectively arranged on the two bases, and the screw nut driving assembly 200 is used to drive the two bases to approach or move away from each other, so as to achieve the purpose of adjusting the distance between the two clamping moving mechanisms 100. Here, one of the bases and the clamping moving mechanism 100 is explained. The annular slide rail 400 , the driving assembly 200 and the second top block 430 in the clamping and moving mechanism 100 are all arranged on the base, which will not be further described here.

[0043] It should be explained that in the prior art, the stability of the driving system in the coating production line has a significant impact on the film conveying speed. If the driving system is unstable due to power supply voltage fluctuations, poor heat dissipation, etc., the conveying speed of the film will fluctuate. On the other hand, if the sensitivity of the tension sensor of the tension control system in the coating production line is reduced, the tension control system will deviate from the control of the film tension, thereby causing the film tension to change, which will also cause the conveying speed of the film to fluctuate. In the prior art, a pressure roller device is usually set at the outlet of the air flotation oven 10. The pressure roller device includes two pressure rollers that can actively rotate. The two pressure rollers are pressed on the film sent out from the air flotation oven 10 to prevent the vibration of the film in the air flotation oven 10 from being transmitted to the film in the subsequent automatic winding device. If the conveying speed of the film deviates, since the rotation speed of the two pressure rollers remains unchanged, the two pressure rollers will be relatively displaced with the film. After the two pressure rollers and the film are relatively displaced, the friction between the two pressure rollers and the film increases, and the two pressure rollers will exert a dragging force on the film that hinders the movement of the film, which can easily cause wrinkles, scratches or even ruptures on the film.

[0044] As another embodiment of the first clamp arm 310 and the second clamp arm 320 in the embodiment of the present invention, refer to Fig.10 and Fig.11 The clamping assembly 300 also includes a first driven belt 311 and a second driven belt 321. The first driven belt 311 and the second driven belt 321 are both parallel to the first straight segment 410. The first clamping arm 310 is provided with a first mounting groove, and the second clamping arm 320 is provided with a second mounting groove. The first driven belt 311 can be rotatably connected in the first mounting groove, and the second driven belt 321 can be rotatably connected in the second mounting groove. The first clamping arm 310 is abutted against one side of the film through the first driven belt 311, and the second clamping arm 320 is abutted against one side of the film through the second driven belt 321, so that when the first clamping arm 310 and the second clamping arm 320 are relatively displaced from the film, the first driven belt 311 and the second driven belt 321 can rotate.

[0045] Here, the clamping assembly 300 on one of the first straight segments 410 is used for illustration. Since the driving speed of the driving assembly 200 remains unchanged, the moving speed of the slider 350 on the first straight segment 410 remains unchanged. If the conveying speed of the film fluctuates, the first clamping arm 310 and the second clamping arm 320 in the clamping assembly 300 will be relatively displaced with the film. After the first clamping arm 310 and the second clamping arm 320 are relatively displaced with the film, since the first clamping arm 310 and the second clamping arm 320 are respectively against one side of the film through the first driven belt and the second driven belt, that is, the first driven belt and the second driven belt clamp one side of the film, and the first driven belt and the second driven belt can both rotate, the first driven belt and the second driven belt can start to rotate under the action of the film. The rotating first driven belt and the second driven belt can automatically adjust the rotation speed according to the fluctuation of the film speed, so that the first driven belt and the second driven belt can better follow the movement of the film. For example, when the conveying speed of the film increases, the first driven belt and the second driven belt can respond quickly and rotate faster to reduce the relative sliding between the first driven belt and the second driven belt and the transmission belt, so that the friction between the first driven belt and the second driven belt and the transmission belt is transformed into rolling friction, which greatly reduces the friction between the first driven belt and the second driven belt and the film, avoids the first driven belt and the second driven belt from generating dragging force on the film, and further avoids wrinkles, scratches or even ruptures of the film after speed fluctuations.

[0046] In the embodiment of the invention, the clamping assembly 300 includes a plurality of first synchronous rollers and a plurality of second synchronous rollers, both ends of the plurality of first synchronous rollers are rotatably connected to the inner side wall of the first mounting groove, the first driven belt is wound around the plurality of first synchronous rollers, the outer wall of the first synchronous roller is provided with teeth, the inner side of the first driven belt is evenly provided with tooth grooves, the teeth on the outer wall of the first synchronous roller can extend into the tooth grooves on the inner side of the first driven belt, so that the first driven belt and the plurality of first synchronous rollers can rotate synchronously. Both ends of the plurality of second synchronous rollers are rotatably connected to the inner side wall of the second mounting groove, the second driven belt is wound around the plurality of second synchronous rollers, the outer wall of the second synchronous roller is provided with teeth, the inner side of the second driven belt is evenly provided with tooth grooves, the teeth on the outer wall of the second synchronous roller can extend into the tooth grooves on the inner side of the second driven belt, so that the second driven belt and the plurality of second synchronous rollers can rotate synchronously, which will not be further described here.

[0047] The present invention also discloses a double-release and double-receiving coating production line, including two continuous coating devices, one of which is arranged above the other continuous coating device, and both of the two continuous coating devices include an automatic unwinding device, a preheating oven, a coating device 20, an air-floating oven 10, a deviation-correcting device, an automatic rewinding device, and a film vibration blocking device, and the automatic unwinding device, the preheating oven, the coating device 20, the film vibration blocking device, the air-floating oven 10, the deviation-correcting device, and the automatic rewinding device are arranged in sequence along the conveying path of the film. In an embodiment of the present invention, the double-release and double-receiving coating production line includes two continuous coating devices that can independently perform coating processing on the film, so the coating efficiency of the film can be significantly improved. Each continuous coating device includes an automatic unwinding device, a preheating oven, a coating device 20, a film vibration blocking device, an air flotation oven 10, a deviation correction device, and an automatic winding device, which are arranged from back to front. The film vibration blocking device can prevent the film between the coating device 20 and the air flotation oven 10 from vibrating, which is beneficial to improving the coating quality of the coating device 20, and further beneficial to improving the quality of the film products processed by the continuous coating device. The automatic unwinding device, the preheating oven, the coating device 20, the air flotation oven 10, the deviation correction device, and the automatic winding device are all common devices in the field of coating technology, and will not be further described here.
